# NoiseInjection

Breaking local optima

Layer: Mind · Category: Strategy

## Mechanism

If the [Agent](https://mindscape.world/scapes/bootstrap/Agent.md) detects it is looping or repeating text, it deliberately injects high-temperature [Noise](https://mindscape.world/scapes/bootstrap/Noise.md) or a random oblique [Strategy](https://mindscape.world/scapes/bootstrap/Strategy.md) [Card](https://mindscape.world/scapes/bootstrap/Card.md) into its [Context](https://mindscape.world/scapes/bootstrap/Context.md) to force a trajectory change.

## Invariants

- Fires on a detected loop or repetition, not as a standing perturbation.
- Injects at most `temperature` worth of [Noise](https://mindscape.world/scapes/bootstrap/Noise.md), leaving the [Signal](https://mindscape.world/scapes/bootstrap/Signal.md) recoverable.
- Returns to a coherent trajectory after the injection.
- Waits `cooldown` before injecting again.

## Preconditions

- Clean signal/process
- Need for exploration/robustness

## Postconditions

- Perturbed output

## Failure modes

- Derailment into nonsense: the injection is large enough that the [Signal](https://mindscape.world/scapes/bootstrap/Signal.md) does not return.
- False positive: legitimate repetition is read as a loop, and a working trajectory is perturbed.

## Parameters

- `temperature` (Ratio, (0.0, 1.0]): Magnitude of the injected noise, as a share of full randomness.
- `detection_threshold` (Ratio, (0.0, 1.0)): Similarity between successive outputs that counts as looping.
- `cooldown` (Duration, unspecified): Minimum interval between injections, so noise does not become the trajectory.
